"Fig; 7'is a fragmentary View of a portion of Figg3 illustrating another embodiment ofthe devioe." f h The holding means; for gates is intended for application upon the top of a gate at the ends t'hereotandfeaoh holding means consists fof a bra'cke't lO forattachment upon the top of the gate anol formed with a passage 11, rods 12' extenclingthru the passage and formed with end fingers 13, and'mea'ns 18 for holcling'th-e rods in Various fixed positions f InFig. '1 numeral' l i indicates a'wall provided witha door opening 15" andadoor 16:. door'may'eorn nunicate with aneley'a- H 4 tor shaft, or the like. During theni ghttime itis customaryto close such doors butdur-f ing the da time-the are'lei't. open. While in an open position, it is necessary to I guard against persons aecidentally walking fthru andjf alling down the elevator shaft or other similanoceurrenee. [For this "reason a gate 117 'is inserted across" theframe of the door when the doojr is in its openlpositionr This gaternay be of conventional] construction, Itis'provi olecl with'a holding means 18 on each end and, onthe topqthereof. These 8 holding-means seriie to maintain the gate in position and{ permit easy removal 1 thereof duringthe oonstruction 'of a building Thefsaid bracket j10"ofthe holding means I8eonsists ofa base plate 19. formed with apertures "20 for the passage of screws for the attachment upon the top of the gate; An

invert d U shaped member Ql is positioned upon theisaid plate 1 9.an'ol provides the said passagell. This member 21 isformed with Bottom, gs 22exte'nded t u apertures in the plate 1 am then riveted over for maintaining its position; It is also "proyided with aboss23 at'.itstop. I 1

The's id ro s]; 12 are formedwith serrated Q portionsf24or portions roughened in any Y other manner. These rods are arranged one above the other as maybe olearlyseen from V anf 'inspeetion ofFigi 5. A portion of the 10G contacts therewith. This roughened portion is indicated by reference numeral 25.

The said fingers 13 are integral with the rods 12 and are directed at right angles thereto. They are substantially parallel to each other and when engaged upon a door frame are positioned on opposite sides there of. The said" means for holding the rods in various fixed positions consists of a'button 26 arranged between thestop rodil2 and'the' bottom of the bend of the U shaped member 21. The top surface 27 011 the-buttonisinclined as shown in Figs. 3', The bottom surface of the boss 23 is provided with a' siini lar: incline 28.. An arbor 2.9 is fixed oILthe top of the button andextnds-thrn. the boss 23.,qAhan-dle 30 is attachedupon. thefi'e'e screws34.threadedly engage'the lugs.
